OLED vs. QLED
Comparing 2 standards across 12 specifications. 12 key differences identified.
Comparing:
OLED
QLED
OLED (Organic Light-Emitting Diode) panels are self-emissive -- each pixel produces its own light and switches fully off for true black -- eliminating the backlight every LCD type requires. Response times run near-instantaneous, but organic material degradation makes burn-in a real, documented long-term risk.
QLED, despite its OLED-like name, is not a self-emissive technology -- it's a conventional LED-backlit LCD panel with a quantum-dot film added between the backlight and the LCD layer to produce more precise color. Samsung introduced it in 2017; it still requires a backlight and has the same blooming limitations as other backlit LCDs.
